Improvements in Boot-Lasters; and I do hereby declarethat the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings `and to the letters of reference markedthereon, which form a part of this specification.

'lhe nature of my invention consists in the construction and use ofdevicesY whereby the uppers of boots or shoes may be drawn tightlyaround vthe last during the manufacture of boots andshoes,

In the accompanying drawings-- Y v Figure 1 is-an elevation of myinvention.

`Letter-sof reference denote parts.

`Acnrved har, A, of suitable material, formsthe to each extremity, A1,of l main body of my device, which are hinged, in any suitable manner,and pro,- jecting downward'ithereirom, curved links A2, one to leach,the lower inside' portions of which are serrated,

at R. Midway, or thereabouts, A, ofthe said links A", are hingedthereto, or pivoted thereto in any suitable manner, other-'curved linksB, of any suitable material, and having their lower parts serrated, tomatch or mesh with the serrations of the links A.

To the upper portions of these links B are connected, in anysuitablemanner, V rods B', ofrany suitable construct-ion, projectingupward diagonally therefrom, and connected in any suitable manner, C',to

a cross-brace, C, which lies above said curved har A, which hasslots Sthrough which said rods B' pass, said cross-braoe O being provided at`or nearits center with a hole, having female screwhthreads therein,through which passes an ordinary screwed stock, D,

,having a .handle at its upper/part, .and being i'rmly confined, inanysuit-able manner, at its lower part, to the said curved v'bar A; thewhole being 4so arranged that the leather encircling the last, beingplaced between the serrated i by the revolution of the screw D, thelinks Az and close together, holding firmly the leather therein; at

the saine time, and by the same operation, the said links moveinwardly,,tightening thereby the leather around the last.

Having thus described my invention,`

What I claim as' new, and desire to secure by Letters Patent,is

The curved bar A, with the links A and B, rods B', in combination withthe cross-bar G and screwedv stock D. when constructed, arranged, andoperating-l substantally as andfor the purpose described and 'set forth.y i
